If the temperature of the measured motor exceeds the environment by more than 25 degrees, the temperature rise of the motor during the cover temperature test has exceeded the normal range. Generally, the temperature rise of the motor should be below 20 degrees. Generally, the motor coil is wound by enameled wire, and when the temperature of the enameled wire exceeds about 150 degrees, the paint film will fall off due to the high temperature, causing the coil to short circuit. Therefore, when the coil temperature is above 150 degrees, the temperature of the motor housing is about 100 degrees. If the housing temperature is considered, the maximum temperature of the motor controller is 100 degrees.

　　The temperature of the motor should be below 20 degrees, that is, the temperature of the motor end cover should be less than 20. But what is the reason why the motor has more than 20 revolutions?

　　 Generally, it may be caused by short-circuit or open-circuit of the coil, demagnetization of the magnetic steel, or low efficiency of the motor. Normally, it is the long-term operation of the motor with high current.

　　What causes the motor to commit this process?

　　 When downloading, there is motor consumption in the motor, which will turn into heat energy, which will cause the temperature to rise and reach the ambient temperature. The ambient temperature of the motor has a high value of infrared heat. At the coming temperature, the motor will dissipate faster than when the motor is alone, and the chasing temperature will no longer increase and maintain a constant temperature, that is, a balance of heat generation and heat dissipation will occur. status.

　　 What is the allowable temperature rise for general clicking? The temperature rise of the motor has a great influence on which part of the motor? Is it defined?

　　Answer: When running with a load, start from the role of playing with it, and then output the attack station with the load (if the mechanical strength is not considered). But output power fights, power consumption attacks, and temperature. We know that the insulation material temperature-resistant motor continues. In this heat, the physical, chemical, mechanical, electrical and other aspects of the insulation material always remain stable, and its service life is generally about . For 20 years.

　　 After this time, the life of the insulating material will be consumed, and it will even burn down for this temperature duration, the allowable temperature of the special insulating material. The temperature of the insulating material is the allowable temperature of the motor; the life of the insulating material is generally the life of the motor.
